Oracle (Arkham)

Barbara Gordon was the daughter of Gotham City's Police Commissioner James Gordon, and was forbidden by her overprotective father from joining the GCPD. Instead, she took on the identity of Batgirl and was a crime-fighting partner of Batman's for years. But that all ended when the Joker shot her through the spine. Paralyzed from the waist down and using a wheelchair, Barbara adopted the new identity of Oracle, and aided the Dark Knight with her computer expertise, which provided Batman with a constant stream of information in the field to aid his battle against crime.
